Myles,
Thanks for the reply and info on your method of capturing design features of your models. The match feature of SketchUp sounds like a very useful option.
I have only been using Autodesk Fusion 360 a short time and isn't user friendly at this point. I will have to look deeper into any input or export options available, something like the match feature would be speed the up the process for a new bee like me. I have been using Autocad light for 2D drawing which has many drawing aids that I would have thought could have been incorporated in the sketch mode for Fusion. It seems like 3D software designers didn't learn from the older 2D methods.
Thanks again Gerry
